OXYVAP® Performance


The two graphs below show the saturation efficiency and pressure drop as a function of frontal air velocity under the Australian
Standard AS 2913-2000. The superior evaporation efficiency of the patented OXYVAP® media is reflected in the relatively high saturation efficiency, even at a higher air velocity. The required fan power is minimized by its extremely low pressure drop, maximizing energy efficiency.
Third party evaluations under Australian Standard AS 2913-2000 (TNO Netherlands and CSIRO Australia) have indicated a saturation efficiency between 89% and 93%.

The evaporative media is based upon our unique and patented water retaining finned aluminium sheet designed for maximum evaporation. At an air velocity of 2 m/s, we reach a saturation efficiency of 89% with an air pressure drop of only 45 Pa.

The high quality aluminum fins in combination with its unique and patented structure allow for a self-cleaning process during the operating mode, hence preventing the buildup of dirt, mold or calcium, which is typically a problem in competitive evaporative cooling media.

Furthermore, thanks to the high water retaining capacity of the fins you don’t need to install a droplet eliminator for air speeds up to 3 m/s.


Cooling Performance

The table below shows the cooling performance of the OXYVAP evaporative media. The supply temperature is shown for a range of combinations of outdoor air temperature and relative humidity, each for three face velocity values:
